`underset(6)CH_(3)-underset(5)CH_(2)-overset(O)overset(||)underset(4)C-underset(3)CH_(2)-overset(O)overset(||)underset(2)C-underset(1)CH_(3)`

Text Solution

Verified by Experts

The functional group present is ketone `(gtC=O)`, hence suffix ‘-one’. Presence of two keto groups is indicated by ‘di’, hence suffix becomes ‘dione’. The two keto groups are at carbons 2 and 4. The longest chain contains 6 carbon atoms, hence, parent hydrocarbon is hexane. Thus, the systematic name is Hexane- 2,4-dione.
